...QlikView is Different from SQL Understand How QlikView works with(out) a Data Warehouse Not Throw Baby out with the Bathwater Adopt Applicable Data Modeling Best Practices Know Where to Go for More Information QlikView is not SQL (SQL Schemas) SQL take a large schema and queries a subset of tables. Each query creates a temporary “Schema” of only a few tables. Query result sets are independent of each other. Query 1 Query 2 QlikView is not SQL (QV Schemas) QlikView builds a smaller and more reporting friendly schema from the transactional database. This schema is persistent and reacts as a whole to user “queries”. A selection affects the entire schema. QlikView is not SQL (Aggregation and Granularity) Store Table Store A B SqrFootage 1000 800 Sales Table Store A A A B B Prod 1 2 3 1 2 Price $1.25 $0.75 $2.50 $1.25 $0.75 Date 1/1/2006 1/2/2006 1/3/2006 1/4/2006 1/5/2006 Select * From Store, Sales Where Store.Store = Sales.Store will return: SqrFootage 1000 1000 1000 800 800 Store A A A B B Prod 1 2 3 1 2 Price $1.25 $0.75 $2.50 $1.25 $0.75 Date 1/1/2006 1/1/2006 1/1/2006 1/1/2006 1/1/2006 Sum(SqrFootage) will return: 4600 If you want the accurate Sum of SqrFootage in SQL you can not join on the Sales table in the same Query!

...This assignment helps you understand what table columns deserve an index through a series of exercises on a database schema. You do not type SQL in this assignment, but rather identify which columns deserve indexes, the type of index it deserves, and why. Correct placement of indexes is absolutely critical to database performance. All but the smallest of databases would have terrible performance if no indexes were assigned to any of its table columns. An index is a physical construct that serves two purposes – speeding up data retrieval and enforcing uniqueness. Indexes are not modeled in logical entity-relationship diagrams, because indexes do not operate at the logical level of abstraction, as do tables and table columns. While the primary purpose of creating an index is to speed up data access, modern relational DBMS also support a type of index that additionally enforces a uniqueness constraint. A uniqueness constraint can be assigned to a table column directly, or is indirectly assigned to a table column when it is assigned a primary key constraint. While a uniqueness constraint is a logical construct, many modern relational DBMS physically implement this constraint through an index. You might reasonably ask the question, “Why not simply add indexes to every column in the schema?” After all, then we would not need to concern ourselves with index placement. The primary reason is that while indexes speed up reading from the database, indexes slow down writing to the database...

...Databases Databases are used to organize a collection of data, allowing for easy access, retrieval, and use of information. The first databases were slow at processing information and inconsistent when applications would require the same information, but kept in different files. Relational databases, normalization, and Structured Query Language have improved the efficiency of databases. To be a proficient database programmer, one should have a basic understanding of rational databases, normalization, Structured Query Language, and the use of database models. Relational Database The use of shared files reduced the problem with inconsistencies but was still not an efficient in accessing information. In the 1970s, a man named Ted Codd came up with the idea of the relational model for databases (Ward & Dafoulas, 2006). Similar to a spreadsheet, the relational model was based on tables, rows, and columns. Relational databases, allows the user to compare information quickly because of the logical arrangement of data in columns. The speed at which data was accessed was made possible by the development of the structured query language (SQL) query language. Because of the uniformity of relational database, completely new tables can be created from information already in existing tables. In other words, the database uses the relationship of similar information to increase the speed and use. The process of normalization was developed to standardize databases. Normalization ...

...This week the discussion moves to an extremely important part of relational database and that SQL, it stands for Structured Query Language and is a declarative programming language intended for the management of databases. Unlike other languages that use imperative programming, with declarative programming the end-user is establishing the code that is telling the computer what you would like to happen. Structured Query Language is a relatively simple language that a majority of all relational databases utilize in order to influence data in a database (“What is SQL?,” n.d.). This leads to the question as to why SQL is such a powerful language this is because SQL make available the ability to manipulate any portion of a database through the use of simple commands. Through the use SQL programming language a plethora of functions in a database such as creating and deleting tables, updating and changing data and retrieving specific data to name a few. By probably the single most powerful expression available to the database programmer in SQL is the employment of the “JOIN” command. At this point you may be thinking to yourself what makes this directive so powerful this is because the function allows the user to process a significant amount of data in a swift and efficient manner. While many individual databases may include two or four tables meanwhile businesses may have hundreds or even thousands of table with need to process data across these table this ultimately...
